PETERJ,
Airproxs are a fact of life, especially outside of controlled airspace. I do not wish to suggest that they are not significant and it's quite right that they are investigated and lessons learnt.
Unfortuantly, after the recent sad event in Germany the press will now pick on these events and
may not provide a full and balanced picture.
Two web sites that will put things in context:-
